FID on world’s largest offshore wind plant in the Netherlands

Vattenfall has taken the final investment decision for the Hollandse Kust Zuid 1-4 offshore wind project proceeding with the construction in the Netherlands.

With its installed capacity of 1,500 MW, Hollandse Kust Zuid will be the largest of its kind worldwide. It will have a renewable electricity output equivalent to the annual consumption of over two million Dutch households.

Vattenfall was awarded permits for the construction of Hollandse Kust Zuid after winning two subsidy-free tender rounds in 2018 and 2019. The two projects have been combined into one wind farm to optimize the process.

In 2023, Hollandse Kust Zuid will provide a third of the total installed offshore wind capacity in the Netherlands, making a major contribution to the Dutch Government’s renewable energy targets. The construction will be initiated offshore in 2021.

Gunnar Groebler, Senior Vice-President and Head of Business Area Wind in Vattenfall said, “Hollandse Kust Zuid will not only provide fossil-free and affordable electricity to our private and business customers. It’s also a large infrastructure investment that creates significant economic activity and employment in times of economic uncertainty. Thanks to good cooperation with our national and international partners, we are well prepared to take the next step in realizing this milestone project.”

Vattenfall has partnered with Siemens Gamesa for turbine manufacturing and partial installation, Sif Group for foundation manufacturing, TKF for inter-array cable systems manufacturing, Prysmian for inter-array cable systems manufacturing, Subsea 7 for foundation and inter-array cable systems installation and Swire Blue Ocean for turbine installation. The wind farm will be connected to two offshore substations operated by Dutch TSO TenneT.
